Comment (by dtakahashi42@…):

 I misunderstood llvm-3.2. It supports autovectorization, and here is a
 preliminary patch on gsl/Portfile to compile it by clang-3.2. Although a
 libtool in the distribution needs to be patched to ignore {{{-mllvm}}}
 flags ([http://lists.gnu.org/archive/html/libtool-
 patches/2012-12/msg00001.html lists.gnu.org]), build process succeeds
 without any errors, and resultant binaries include many AVX instructions.

 However, those binaries fail some of the {{{make check}}}. Because a gsl
 with {{{+gcc47 +optimize}}} passes all those tests, it would be a problem
 of binaries built by llvm.

 Here, I attach a new patch on gsl/Porifile, a patch on libtool, and output
 of {{{make check}}}.
